CATCH FOR CASTING HEARTH-PLATE (lATCHES AND GRATE-HOOKS.

SPECIFICATION forming part of Letters Patent No. 338,210, dated March 16, 1886. Application filed December 30, 1885. Serial No. 187,133. (No model.)

To all whom it may concern:

Be it known that I, CASPAR VETTER, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Casting Hearth-Plate and Grate Hooks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improved means for casting hearth-plate catches and gratehooks, and is a box or casing to be used in connection with the patterns of the grate and hearth, and left in the mold when the patterns are withdrawn from the sand, thus causing said casing to adhere to the casting.

With these ends in view the invention consists in a peculiar construction of box or casing adapted to be applied to a projecting standard on the grate or hearth, so that when the metal is poured into said box or casing a hook or catch will be formed integral with the standard.

In the drawings, Figure 1 is a side elevation of aportion of a pattern for a hearth with my improved box or casing shown applied to the arm or standard thereof. Fig. 2 is a transverse vertical section of the same. Fig. 3 is a plan view of the same. Fig. 4 is a side elevation of the box or casing for casting grate-hooks, the same being shown applied to the pattern of the grate; and Fig. 5 is a section of the same.

Corresponding parts in the several figures are denoted by the same letters of reference.

Referring to the drawings, A represents a portion of the hearth-plate pattern, and B a standard or upright projecting therefrom and formed integral therewith.

0 represents the box or casing for casting the hook or catch on the upper end of this standard or post. This box or casing G is composed of the sides a, which are of greater length than the width of the post or standard, and are cut off obliquely at their upper outer ends.

D represents the top of the box or casing, which is provided with a hole or opening, b, the sides of said opening being turned inwardl y, so that they will support the box or casing above the post and leave a space, 0. The top of the box or casing extends downwardly, and is joined to the inclined edges of the sides in any suitable manner. The top or strip composing the same is then bent inwardly, so as to close the space between the lower edges of the sides where they project beyond the post, and the end of said strip is then bent downwardly to form a flange, d, which, when the casing is placed on the post or upright,bcars against the side of the latter and holds the casing in position.

The gratehook shown is similar in construction to the hearth hook or catch already described, and only differs therefrom in the configuration of the sides, which are rounded on their upper projecting ends.

It will be seen that by making the opening 1) and turning in the sides of the same a space is left between the top of the casing and the standard B, so that when the metal is introduced into the mold it will fill around the inturned sides and cause the casing to adhere to the casting, said opening also serving as a vent.

The manner of casting the hook or catch with the post or upright is similar to that described in Letters Patent No. 321,549, issued to me July 6, 1885.

Having thus described my invention, I claim- The sheet-metal casing described,consisting of the sides of desired form, a strip connect- 85 ing the sides, an opening in said strip, and the flanges formed by turning in the sides of said opening, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

OASPAR VEITER.
